Whenever I run my program it gives me the following error:
Exception in thread "main" java.util.NoSuchElementException at java.util.StringTokenizer.nextToken(StringTokenizer.java:349) at runCar.main(runCar.java:40) the assignment says that I need to close the file, but I am unsure on how to do so, and I haven't found any answers online.
Here is my current code:

while (code.charAt(0)!='X'){
System.out.println();
System.out.println(line);
